Ozawa Shuzo

小澤酒造

Ozawa Shuzo in Ome produces the beloved Sawanoi (Swamp of Joy) brand using limestone-filtered water from a cave beneath the brewery along the Tama River gorge. As Tokyo's most prominent sake brewery, Sawanoi draws visitors from the capital for tastings in a scenic riverside setting. Their sakes are clean, balanced, and carry a distinctive mineral character from the cave water.
